Contributed by Wim Lewis, add support for checking device
signatures in detail (patch #4924 and #4925)
* avrdude.conf.in: Add signatures
* avrpart.c: Set default signature
* avrpart.h: Variable for signature
* config_gram.y: More signature reading
* lexer.l: Define that signatures exist
* main.c: Read signatures and check them against hardware

. Implement the new EECRAddress field in the device descriptor that is
required by the 4.x firmware; make an uneducated guess about what
firmware requires what length of device descriptor -- perhaps Atmel
can be convinced to publish an official matrix for that.
. Specify EECR in the config file where required. Obviously, only
locations that differ from the 0x3c default are mentioned in the
XML files, so by now, this only affects the AT90CAN128 for us.
. After clarification with Atmel, EnablePageProgramming should really
default to 1, and only cleared if specified by an XML parameter. So
far, only the XML files for the ATmega256x and ATmega406 do specify
it at all, and they specify a 1, too.
. Drop the entire OCDEN fuse heuristic. If OCDEN is unprogrammed at
startup, issue a warning that single-byte EEPROM updates won't be
possible. Leave it to the user to program the fuse if desired.
That way, we won't run into any issue of prematurely wearing out the
hfuse EEPROM cell. Interestingly enough, this also solved the
problem of the target not restarting from scratch upon sign-off.

Walthinsen, as well as JTAG ICE mkII support (by me).
Erik's submission has been cleaned up a little bit, mostly to add his
name and the current year to the copyright of the new file, remove
trailing white space before importing the files, and fix the minor
syntax errors in his avrdude.conf.in additions (missing semicolons).
The JTAG ICE mkII support should be considered alpha to beta quality
at this point. Few things are still to be done, like defering the
hfuse (OCDEN) tweaks until they are really required. Also, for
reasons not yet known, the target MCU doesn't start to run after
signing off from the ICE, it needs a power-cycle first (at least on my
STK500).
Note that for the JTAG ICE, I did change a few things in the internal
API. Notably I made the serial receive timeout configurable by the
backends via an exported variable (done in both the Posix and the
Win32 implementation), and I made the serial_recv() function return a
-1 instead of bailing out with exit(1) upon encountering a receive
timeout (currently only done in the Posix implementation). Both
measures together allow me to receive a datastreem from the ICE at 115
kbps on a somewhat lossy PCI multi-UART card that occasionally drops a
character. The JTAG ICE mkII protocol has enough of safety layers to
allow recovering from these events, but the previous code wasn't
prepared for any kind of recovery. The Win32 change for this still
has to be done, and the traditional drivers need to be converted to
exit(1) upon encountering a timeout (as they're now getting a -1
returned they didn't see before in that case).
